Abstract

Objective: Explore the effects of vibration mill's vibration mass on superfine grinding performance of wheat bran. Methods: A series of vibration impact grinding experiments of wheat bran was carried out by adjusting the grinding medium mass and wheat bran mass, respectively. Results: When the wheat bran mass was unchanged, the yield of wheat bran superfine powder showed a non-linear characteristic of first increasing and then decreasing with the increase of the quality of the grinding medium, and the maximum difference rate reached 123.53%. The quality of wheat bran micro powder also increased firstly and then decreased with the increase of grinding medium mass. However, when the grinding medium mass was unchanged, the yield of wheat bran superfine powder showed characteristic of first decreasing and then increasing with the increase of the quality of the grinding medium, and the maximum difference rate reacheds 588.69%. With the increase of wheat bran mass, the quality of wheat bran micro powder decreased firstly and then increased. It was also found that the sensitivity of wheat bran superfine powder yield to wheat bran mass was higher than that of wheat bran superfine powder yield to grinding medium mass. Conclusion: The grinding medium mass and wheat bran mass of vibration mill have significant effects on the superfine grinding of wheat bran, but the effect levels are different.
